Spectra extracted from the NW bubble region. Line profiles of H2 (top) and Paα (bottom) are shown at the position of the three spaxels labeled in Fig. 10. The black dashed curves represent the spectra from the original cube, highlighting the contribution attributed to the HGO (red-shaded area) that we have already isolated and subtracted; the black solid lines represent the spectra fitted to identify the NW bubble. The red Gaussian profiles identify the isolated NW bubble, while orange profiles identify the rotating disk component. The combined model is displayed in green. The velocities are computed with respect to the systemic velocity of the E nucleus.
